SPECIFICATTUIJ forming part of Letters Patent No. 323, 031, dated July 28 1885.

Applicnth n filed May 2), 1884.

To all whom it may concern:

Be it known that I, Qonnsn PrLoRIM, of East New York, in the county of Kings and State of New York, have invented a new and useful Improvement in Torpedoes, of which the following is a specification.

My invention relates to those torpedoes in which the fulminate is inclosed in a sack or wrapper separate from the sand or gravel filling.

The invention consists in the combination, in a torpedo, of the following elements, namely: afuln1inate pellet, a waterproof wrapper inclosing the iulniinate pellet, a sand or gravel filling, and an outer envelope or wrappers inclosing both the filling and the water-proof wrapper with its contained fut ininate.

The waterproof wrapper for the fulniinate may be of woven fabric or paper, and, being waterproof, it protects the fulininate against becoming impaired by moisture, and enables it to be used in a new torpedo or otherwise exploded in case the outer wrapper heroines broken.'

In. the accompanying drawings, Figure l is a sectional view of a torpedo embodying my invention. Fig. 2 iso sectional view of the i'ulminatewrapper and fuhninate, and'Fig. 3 is a plan of the inner wrapper and contained fulminate.

Similar letters of reference designate corresponding parts in the several figures.

In making torpedoes I prefer to inolose the fulminate in woven fabric, which is stronger and tougher than paper; but paper of" any suitable kind. may be used in lieu of cloth, The inner wrapper, which holds the fulniinate separate from the sand or gravel filling, whether it be of paper or of woven fabric, will be rendered waterproof.

A. designates the fnlminate. B designates the wrapper which contains it. C designates the sand or gravel which forms the filling of the torpedo; C, an inner wrapper; and D designates the outer wrapper, which inclosos the whole.

The wrapper B, for the fulniinate, consists of two pieces of i'aln'ic or material cemented or stuck'together, so as to form a closed wrap per and. rendered water-proof. The fulnin nate maybe incloscd in a wrapper of mate the drops of il'llniiuatc.

rial which is not waterproof, and the wrapper,with its contained l'ulniinatc,then dipped into a hath of parafiine or other water-proof substitute; or I may take two sheets or pieces of paper or woven fabric, which are thoroughly saturated. with water-proofsubstance, and, after depositing the gobs or drops of fulniiinate at proper distances apart on one sheet or picce,lay the other sheet or piece thereonto, and. cement or secure the two sheets or pieces together by adhesive substance, the sheets or pieces being subsequently divided between lhe water proof wrz'tppor B, with its contained i'nlininaie A, is then inclosed with the sand or gravel G in the inner wrapper, (1, and around all is placed the outer wrapper, D, which is secured by twisting and adhesive substance, The outer wrapper, D, may be of material which is saturated with paraftlne or other water-proof substance; or the torpedo may have waterproof substance applied to its exterior after it is in other respects completed. The inner waterproof wrapper protects the fulniinate, whether the outer wrapper be water-proof or not, and even if the outer wrapper should break the fulrninate will be protected from moisture by its individual waterproof wrapper, and can be put in a now enter wrapper with fresh gravel,or exploded. in any other way.

In my Letters Patent No. 291,853, dated January 8, 1884, I have shown and described a torpedo in which the fulrninate and sand or gravel filling are together inclosed in a water proof. wrapper. In that patent the gob or drop of fulininate is placed on a small piece of linen or other fabric, and this, together with the grave]. or sand,is inclosed in a wrapper, the fulniinate not bein g separate from the filling, but in contact therewith.

The torpedo whichjfornis the subject of my present invention is distinguished from that shown in my former patent in that the'fulrninate is entirely inclosed in awater-proof wrapper separate from the filling. This separate water-proof wrapper for the iulniina-te is desirable,bccansc it protects the fulrninate from moisture if all the other wrappers of the torpedo break, and can be put in a new outer wrapper with. fresh gravel,or exploded in any other way.

\Vlmt I claim as my invention, and desire waterproof wrapper with its contained ful to secure by Letters Patent, islninate, substantially as and for the purpose [0 In atorpedo, the combination of the followherein described.
